International organizations within and outside the United Nations system provide platforms for multilateral cooperation and give impulses for national policymaking to promote the implementation of the Sustainable Development Goals (SDGs). They set agendas, coordinate efforts across regions and countries, offer technical assistance and expertise, compile data and monitor progress and raise awarenes
Using megahertz x-ray free electron laser imaging with x-ray pulses of ~25 femtoseconds and a machine-learning strategy, we have conducted comprehensive in situ imaging studies on the dynamics of cavitation bubble clouds in ultrasound fields at the SPB/SFX beamline of the European XFEL. The research unambiguously revealed the quasi-simultaneous implosion of multiple bubbles and simultaneous collap
In this paper we study how transforming regular reinforcement learning environments into goal-conditioned environments can let agents learn to solve tasks autonomously and reward-free. We show that an agent can learn to solve tasks by selecting its own goals in an environment-agnostic way, at training times comparable to externally guided reinforcement learning. Our method is independent of the un
Background: Metformin is one of the most used drugs worldwide. Given the increasing use of proteomics in trials, bioresources, and clinics, it is crucial to understand the influence of metformin on the levels of the circulating proteome. Methods: We analysed a combined longitudinal proteomics dataset from the IMPOCT, RAMP and S3WP-T2D clinical trials in 98 participants before and after metformin e
Lean, premixed, swirl-stabilized flames are widely used in modern Dry Low Emissions gas turbine combustors; however, the turbulent combustion process under those conditions is known to be extremely sensitive and prone to instabilities. Numerical simulations can be a valuable tool in predicting the effects of alternative fuels; however, the sensitivity of the results to different models ought to be
We report on recent developments that enable megahertz hard X-ray phase contrast imaging (MHz XPCI) experiments at the Single Particles, Clusters, and Biomolecules and Serial Femtosecond Crystallography (SPB/SFX) instrument of the European XFEL facility (EuXFEL). We describe the technical implementation of the key components, including an MHz fast camera and a modular indirect X-ray microscope sys
Syftet med denna avhandling är att undersöka användningen av naturrättsligt språkbruk i de danska agrarreformerna, cirka 1750-1800. Detta görs genom en social kontextualisering som fokuserar på de sprickor som fanns i det danska samhället före och under reformperioden. Jag hävdar att dessa huvudsakligen utgjordes av interna materiella skillnader inom den danska jordägande eliten, inklusive deras oPopular science description The agrarian reforms of the 18th century were some of the most momentous historical events in Danish history. In the span of 30 years, half of all peasants went from living in a state of serfdom to owning and cultivating their own plots of land, free from the onerous ties of manorial dependence that they had toiled under for hundreds of years. In this pioneering dissert
Here we report the results from exploratory analysis using a Bayesian network approach of data originally derived from a large North European study of type 2 diabetes (T2D) conducted by the IMI DIRECT consortium. 3029 individuals (795 with T2D and 2234 without) within 7 different study centres provided data comprising genotypes, proteins, metabolites, gene expression measurements and many differen
The long-standing debate in the scientific community about whether ferroelectricity or ferroelasticity is the key property influencing the optoelectronic behavior of metal halide perovskites continues. In this study, we experimentally investigate the temperature dependence of photoluminescence from CsPb(Br1−xClx)3 nanowires and their heterojunctions. Our findings show an enhancement of the exciton
Background: Children aged 0–18 years who need long-term respiratory support rely on medical technology and comprehensive medical care. For this care to be provided at home, access to medical and social support and care is essential. In Sweden, the most notable form is personal care assistance (PCA), which is granted based on legislation and individual authority decisions. We aim to explore the imp

We study experimentally and with wave optics modelling the absorption of light in CsPbBr3perovskite nanowire arrays fabricated into periodic pores of an anodized aluminum oxide matrix, for nanowire diameters from 30 to 360 nm. First, we find that all the light that couples into the array can be absorbed by the nanowires at sufficient nanowire length. This behavior is in strong contrast to the expe
Robotic systems often face execution failures due to unexpected obstacles, sensor errors, or environmental changes. Traditional failure recovery methods rely on predefined strategies or human intervention, making them less adaptable. This paper presents a unified failure recovery framework that combines Vision-Language Models (VLMs), a reactive planner, and Behavior Trees (BTs) to enable real-time
The combustion of conventional Jet A, alongside two alternative jet fuels, C1 and C5, is simulated with Large Eddy Simulations (LES) in a generic single-cup spray combustor during idle and cruise conditions. The spray is modeled using Lagrangian particle tracking and the combustion chemistry of each fuel is modeled by skeletal reaction mechanisms. The volatility and atomizability of each fuel dire

Obesity’s metabolic heterogeneity is not fully captured by body mass index (BMI). Here we show that deep multi-omics phenotyping of 1,408 individuals defines a metabolome-informed obesity metric (metBMI) that captures adipose tissue-related dysfunction across organ systems. In an external cohort (n = 466), metBMI explained 52% of BMI variance and more accurately reflected adiposity than other omic
